Abstract
PURPOSE/BACKGROUND The aim of this study was to evaluate the short and midterm results of aortic coarctation (AoCo) stenting in an adolescent and adult population. METHODS All patients with a AoCo older than 14 years treated by stent placement between December 2000 and November 2016 were included in this study. Twenty-eight patients with an invasive peak systolic pressure gradient >20 mmHg were identified. Number of redilations, non-invasive systolic blood pressure, peak systolic pressure gradient, antihypertensive medication intake, claudication status and complications were evaluated. RESULTS Twenty-two covered and 6 uncovered stents were successfully placed. Peak systolic pressure gradient decreased immediately after stenting from a mean of 32 mmHg to 0 mmHg (± 7 mmHg). Mean AoCo diameter increased from 8 tot 16 mm (± 4 mm). Peripheral arterial injury was seen in 2 patients (7.1%). The mean follow-up time was 60 ± 49 months. Redilation of the stent was required in 4 patients, 2 to accommodate for growth and 2 for restenosis. Six (35%) patients could stop all antihypertensive medication. All claudicants (6/28) became and remained asymptomatic after surgery and during their follow-up. No aneurysms, stent fractures or dissections were noticed. There were 2 stent migrations during the first procedure with only 1 needing additional stent placement. CONCLUSION Aortic coarctation stenting is a safe and effective treatment that significantly reduces the peak systolic pressure gradient. Antihypertensive medication can be reduced, and increase of walking distance in claudicants can be obtained. Younger patients may need more frequent reinterventions to accommodate for growth.

Abstract
Background and Aims Abdominal coarctations are rare. Surgical treatment is difficult and requires re‐interventions to adjust the graft material to patient growth. We report effective treatment by interventional catheterization in an infant with the concern to allow adjustment for growth and prevention of vessel damage. Methods and Results After the diagnosis of abdominal coarctation at 27 weeks of gestation, an infant developed hypertension (170/70 mmHg) at 3 months of age despite medical therapy. Angio CT confirmed a 2 mm diameter, 2.3‐cm‐long coarctation of the descending aorta. At 4 months, a dilatation was performed using a 3 mm cutting balloon and a 5 mm Opta® balloon, Cordis®. Two noncovered Palmaz® Genesis™ XD PG1910P stents were required to keep the aortic lumen open. At 15 months, an Adventa™ V12 vascular 12 × 61 mm long covered stent was implanted to exclude an aneurysm which developed between the two stents. At 3 and 9.5 years, the stents were further dilated with a high‐pressure balloon to reach 11 mm aortic diameter with no residual pressure gradient, and normal blood pressure. Conclusions The use of cutting balloons and stent implantation is an effective way to relieve severe obstruction in middle aortic syndrome in neonates. The technical issues encountered were the need for a low profile sheath and material to avoid femoral artery damage, and the need to use stents that can be further expanded to adult size.

Abstract
Importin 8, encoded by IPO8, is a ubiquitously expressed member of the importin-β protein family that translocates cargo molecules such as proteins, RNAs, and ribonucleoprotein complexes into the nucleus in a RanGTP-dependent manner. Current knowledge of the cargoes of importin 8 is limited, but TGF-β signaling components such as SMAD1-4 have been suggested to be among them. Here, we report that bi-allelic loss-of-function variants in IPO8 cause a syndromic form of thoracic aortic aneurysm (TAA) with clinical overlap with Loeys-Dietz and Shprintzen-Goldberg syndromes. Seven individuals from six unrelated families showed a consistent phenotype with early-onset TAA, motor developmental delay, connective tissue findings, and craniofacial dysmorphic features. A C57BL/6N Ipo8 knockout mouse model recapitulates TAA development from 8-12 weeks onward in both sexes but most prominently shows ascending aorta dilatation with a propensity for dissection in males. Compliance assays suggest augmented passive stiffness of the ascending aorta in male Ipo8-/- mice throughout life. Immunohistological investigation of mutant aortic walls reveals elastic fiber disorganization and fragmentation along with a signature of increased TGF-β signaling, as evidenced by nuclear pSmad2 accumulation. RT-qPCR assays of the aortic wall in male Ipo8-/- mice demonstrate decreased Smad6/7 and increased Mmp2 and Ccn2 (Ctgf) expression, reinforcing a role for dysregulation of the TGF-β signaling pathway in TAA development. Because importin 8 is the most downstream TGF-β-related effector implicated in TAA pathogenesis so far, it offers opportunities for future mechanistic studies and represents a candidate drug target for TAA.

Abstract
AIMS Percutaneous pulmonary valve implantation (PPVI) has proven good hemodynamic results. As infective endocarditis (IE) remains a potential complication with limited available clinical data, we reviewed our patient records to improve future strategies of IE prevention, diagnosis and treatment. METHODS Medical records of all patients diagnosed with Melody® valve IE according to the modified Duke criteria were retrospectively analyzed in three Belgian tertiary centers. RESULTS 23 IE episodes in 22 out of 240 patients were identified (incidence 2.4% / patient year) with a clear male predominance (86%). Median age at IE was 17.9 years (range 8.2-45.9 years) and median time from PPVI to IE was 2.4 years (range 0.7-8 years). Streptococcal species caused 10 infections (43%), followed by Staphylococcus aureus (n = 5, 22%). In 13/23 IE episodes a possible entry-point was identified (57%). IE was classified as definite in 15 (65%) and as possible in 8 (35%) cases due to limitations of imaging. Echocardiography visualized vegetations in only 10 patients. PET-CT showed positive FDG signals in 5/7 patients (71%) and intracardiac echocardiography a vegetation in 1/1 patient (100%). Eleven cases (48%) had a hemodynamically relevant pulmonary stenosis at IE presentation. Nine early and 6 late percutaneous or surgical re-interventions were performed. No IE related deaths occurred. CONCLUSIONS IE after Melody® valve PPVI is associated with a relevant need of re-interventions. Communication to patients and physicians about risk factors is essential in prevention. The modified Duke criteria underperformed in diagnosing definite IE, but inclusion of new imaging modalities might improve diagnostic performance.

Abstract
Background: Several techniques have been described to correct coarctation associated with distal arch hypoplasia. However, in neonates, residual gradients are frequently encountered and influence long-term outcome. We reviewed our experience with an alternative technique of repair combining carotid–subclavian angioplasty and extended end-to-end anastomosis. Methods: From 1998 through 2014, 109 neonates (median age, 9 days) with coarctation and distal arch hypoplasia (n = 106) or type A interrupted aortic arch (n = 3) underwent repair using this technique. Thirty patients had isolated lesions (group 1), 44 associated ventricular septal defect (group 2), and 35 associated complex cardiac lesions (group 3). Median follow-up was 98 months. Results: Repair was performed via left thoracotomy in 97%. There was one procedural-related death (0.9%) and overall five patients died during index admission (4.6%). Ten deaths were recorded at follow-up. Actuarial five-year survival was 86% (100% in group 1, 91% group 2, and 66% in group 3). Recurrent coarctation (clinical or invasive gradient >20 mm Hg) developed in 15 patients, all but 2 successfully treated by balloon dilatation. Freedom from any reintervention (dilatation or surgery) at five years was 86%. Only two patients were on antihypertensive drugs at last follow-up. Conclusions: This combined technique to correct distal arch hypoplasia and isthmic coarctation results in low mortality and acceptable recurrence rate. It preserves the left subclavian artery and allows enlargement of the distal arch diameter. Late outcome is excellent with very low prevalence of late arterial hypertension.

Abstract
Cirrhosis in adults is associated with modifications of systemic and liver hemodynamics, whereas little is known about the pediatric population. The aim of this work was to investigate whether alterations of hepatic and systemic hemodynamics were correlated with cirrhosis severity in children. The impact of hemodynamic findings on surgical management in pediatric living donor liver transplantation (LT) was evaluated. Liver and systemic hemodynamics were studied prospectively in 52 children (median age, 1 year; 33 with biliary atresia [BA]). The hemodynamics of native liver were studied preoperatively by Doppler ultrasound and intraoperatively using invasive flowmetry. Portosystemic gradient was invasively measured. Systemic hemodynamics were studied preoperatively by Doppler transthoracic echocardiography and intraoperatively by using transpulmonary thermodilution. Hemodynamic parameters were correlated with Pediatric End-Stage Liver Disease (PELD) score and the histological degree of fibrosis (collagen proportionate area [CPA]). Cirrhosis was associated with a 60% reduction of pretransplant total liver flow (n = 46; median, 36 mL/minute/100 g of liver) compared with noncirrhotic livers (n = 6; median, 86 mL/minute/100 g; P = 0.002). Total blood flow into the native liver was negatively correlated with PELD (P < 0.001) and liver CPA (P = 0.005). Median portosystemic gradient was 14.5 mm Hg in children with cirrhosis and positively correlated with PELD (P < 0.001). Portal vein (PV) hypoplasia was observed mainly in children with BA (P = 0.02). Systemic hemodynamics were not altered in our children with cirrhosis. Twenty-one children met the intraoperative criteria for PV reconstruction using a portoplasty technique during the LT procedure and had a smaller PV diameter at pretransplant Doppler ultrasound (median = 3.4 mm; P < 0.001). Cirrhosis in children appears also as a hemodynamic disease of the liver, correlated with cirrhosis severity. Surgical technique for PV reconstruction during LT was adapted accordingly.

Abstract
Background Some decades ago, the Mustard or Senning operation was used to treat patients who were born with Transposition of the Great Arteries (TGA). Although life expectancy is good, previous studies have demonstrated limitations in exercise capacity. To what extent these limitations affect day-to-day functioning of the patients is not yet known. Aims We therefore investigated self-reported physical activities in patients after the Mustard or Senning operation, compared this with those of matched, healthy counterparts, and explored potential associations with age, gender and complexity of the TGA. Methods Seventy patients were matched with healthy controls. Habitual physical activity was measured using the Baecke questionnaire, resulting in a work, sports, and leisure time index, which ranges from 1 to 5. Results The median index scores of patients were 2.63 for work, 2.50 for sports; and 2.75 for leisure time. Only for sports, a significantly lower index score was found in patients. Furthermore, we found that older patients were less frequently engaged in sport activities (Spearman's rho=–0.38; p=0.02). Conclusion The results showed that the level of physical activities of patients after the Mustard and Senning operation is normal, except for sport activities. This indicates that patients after a Mustard or Senning operation tend to partake in all activities that they can comfortably perform.

Abstract
OBJECTIVES This study evaluated the prognostic value of postoperative cardiac troponin-I (cTnI) in predicting all-cause mortality up to 3 months after normothermic congenital cardiac surgery. DESIGN Prospective observational study. SETTING University hospital. PARTICIPANTS All children ages 0 to 10 years. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS cTnI was measured after the induction of anesthesia but before the surgery, at the pediatric intensive care unit arrival, and at 4, 12, and 24 hours postoperatively. Follow-up was extended up to 6 months. Overall, 169 children were analyzed, of whom 165 were survivors and 4 were nonsurvivors. cTnI levels were significantly higher in nonsurvivors only at 24 hours (p = 0.047). Children undergoing surgery with cardiopulmonary bypass (CPB) had significantly higher cTnI concentrations compared with those without CPB (p<0.001). Logistic regression analysis was performed on the 146 children in the CPB group with the following predictive variables: CPB time, postoperative cTnI concentrations, the presence of a cyanotic malformation, and intramyocardial incision. None of the variables predicted mortality. Postoperative cTnI concentrations did not predict 6 months׳ mortality. Only cTnI at 24 hours predicted the length of stay in the pediatric intensive care unit. CONCLUSIONS This study did not find that postoperative cTnI concentration predicted midterm mortality after normothermic congenital heart surgery. (ClinicalTrials.gov identifier: NCT01616394).

Abstract
In the presence of new surgical techniques, the treatment of congenital valvular aortic stenosis is under debate. We reviewed the results and late outcomes of all 93 patients aged 1 day to 18 years, treated with balloon valvuloplasty (BAV) as first-line therapy for congenital aortic valve stenosis in our center from January 1991 to May 2012. Mean age at procedure time was 2.4 years; 37 patients underwent BAV at age ≤30 days (neonates), 29 patients at age ≥1 month and <1 year (infants), and 27 patients were older than 1 year (children). The invasive BAV peak-to-peak aortic valve gradient (mean 59 ± 22 mmHg) was immediately reduced (mean 24 ± 12 mmHg). The observed diminution of gradient was similar for each age group. Four patients had significant post-BAV AI. Mean follow-up after BAV was 11.4 ± 7 years. The last echo peak aortic gradient was 37 ± 18 mmHg and mean gradient was 23 ± 10 mmHg, and two patients had significant AI. Actuarial survival for the whole cohort was 88.2 and 72.9 % for the neonates. All infants, except one, and all children survived. Sixty-six percent of patients were free from surgery, and 58 % were free from any reintervention, with no difference according to age. Freedom from surgery after BAV at 5, 10, and 20 years, respectively, was 82, 72, and 66 %. Our study confirms that BAV as primary treatment for congenital AS is an efficient and low-risk procedure in infants and children. In neonates, the prognosis is more severe and clearly related to "borderline LV."

Abstract
OBJECTIVES We describe the first report of a transcatheter Sapien implantation in a native tricuspid valve after multiple failed surgical repairs with a lack of prosthetic material and radiographic landmarks. METHODS AND RESULTS A 47-year old female underwent multiple valve repairs and replacements including three tricuspid valve repairs without surgical ring or bioprosthesis implantation. She developed signs of right heart failure associated with a mixed tricuspid disease combining a severe stenosis and regurgitation. After surgical turn down, a revalvulation using a transcatheter approach was attempted. The challenges in this case were the absence of a stiff region to anchor the percutaneous valve, the lack of radiographic landmarks and the difficulties of precise annulus measurements. The applied strategy was -under general anesthesia and extracorporeal membrane oxygenation-: balloon sizing, prestenting of the tricuspid annulus using covered stents followed by Sapien valve implantation through the femoral vein under fluoroscopy and transoesophageal echocardiography (TEE). The procedure was successfull, solving the tricuspid leak and stenosis (peak gradient from 22 to 3 mm Hg) using two Sapien for a perfect positioning. It was complicated by pulmonary bleeding due to a distal wire exit, treated successfully by coil embolization. The clinical and echocardiographic outcome was good up to 5 months. CONCLUSIONS Transcatheter Sapien valve implantation in a native tricuspid valve after failed multiple surgical repairs is feasible by the femoral vein. Technical challenges due to the lack of rigid landing zone and fluoroscopic markers were solved by prestenting and valve implantation under bi-plane fluoroscopic and TEE guidance.

Abstract
AIM The aims of the study were to compare perinatal outcome and assess recipient cardiac disease according to treatment strategy (amnioreduction (AR), laser or selective feticide). METHODS We retrospectively reviewed 81 consecutive cases of twin-to-twin transfusion syndrome diagnosed before 28 weeks between 1993 and 2007. RESULTS Although fetuses treated by laser were younger at diagnosis (median 20.4 vs. 22.4 weeks, P = 0.01), they were significantly older at birth (median 33.6 vs. 28.5 weeks, P = 0.004) than those treated by AR. Neonatal morbidity was globally lower after laser than AR, and cardiac insufficiency tended to be less frequent (31% vs. 57%, P = 0.09). There was a trend towards increased perinatal survival after laser treatment (68% vs. 49%, P = 0.1). Heart failure was the cause of death in half (23/46) of the recipients. Fetal heart failure leading to death was 2.7 times more frequent after AR than after laser (n = 11 vs. n = 4), and all four neonatal cardiac deaths occurred after AR. Compared with laser, selective feticide did not further improve the outcome. CONCLUSIONS Heart failure was an important cause of perinatal morbidity and death. However, laser therapy resulted in a longer diagnosis-delivery interval and lower global neonatal morbidity than AR, with a trend towards increased perinatal survival. Improved outcome after laser treatment compared with AR might be related to its impact on recipient heart disease.

Abstract
BACKGROUND Chronic right ventricular (RV) pacing is associated with deleterious effects on cardiac function. OBJECTIVE In an observational multicentre study in children with isolated atrioventricular (AV) block receiving chronic ventricular pacing, the importance of the ventricular pacing site on left ventricular (LV) function was investigated. METHODS Demographics, maternal autoantibody status and echocardiographic measurements on LV end-diastolic and end-systolic dimensions and volumes at age <18 years were retrospectively collected from patients undergoing chronic ventricular pacing (>1 year) for isolated AV block. LV fractional shortening (LVFS) and, if possible LV ejection fraction (LVEF) were calculated. Linear regression analyses were adjusted for patient characteristics. RESULTS From 27 centres, 297 children were included, in whom pacing was applied at the RV epicardium (RVepi, n = 147), RV endocardium (RVendo, n = 113) or LV epicardium (LVepi, n = 37). LVFS was significantly affected by pacing site (p = 0.001), and not by maternal autoantibody status (p = 0.266). LVFS in LVepi (39 ± 5%) was significantly higher than in RVendo (33 ± 7%, p < 0.001) and RVepi (35 ± 8%, p = 0.001; no significant difference between RV-paced groups, p = 0.275). Subnormal LVFS (LVFS < 28%) was seen in 16/113 (14%) RVendo-paced and 21/147 (14%) RVepi-paced children, while LVFS was normal (LVFS ≥ 28%) in all LVepi-paced children (p = 0.049). These results are supported by the findings for LVEF (n = 122): LVEF was <50% in 17/69 (25%) RVendo- and in 10/35 (29%) RVepi-paced patients, while LVEF was ≥ 50% in 17/18 (94%) LVepi-paced patients. CONCLUSION In children with isolated AV block, permanent ventricular pacing site is an important determinant of LV function, with LVFS being significantly higher with LV pacing than with RV pacing.

Abstract
BACKGROUND Percutaneous transcatheter closure of patent foramen ovale (PFO) and atrial septal defect (ASD) has been shown to be feasible. AIM The aim of this study was to evaluate the safety and efficacy of transcatheter interatrial septal shunt closure with prosthesis implantation in adults patients during long-term follow-up. In addition, the impact of thrombophilia and pulmonary hypertension on the outcome were investigated. METHODS Between June 1999 and November 2009, 287 patients (112 males, 43 ± 14 years) were treated in our institution by transcatheter closure of PFO (N = 175) or ASD (N = 112). Clinical and echocardiographic follow-up were prospectively performed at 1, 6 and 12 months followed by a 1 once a year evaluation. RESULTS All procedures were successful with eight procedural complications (2.7%): one stroke, two femoral pseudoaneurysms, three transient atrial fibrillation, two minors pericardial effusions. Among patients with presumed paradoxical embolism, thrombophilia was observed in 29 patients (17%); only one of them experienced a recurrent stroke. Among patients with ASD, pulmonary hypertension was observed in 32 cases (28%) and significantly reduced 6 months after shunt closure (from 47 ± 7 to 31 ± 11 mm Hg, P < 0.0001). 99% of patients achieved a complete follow-up. Clinical improvement was observed in 93%. Freedom from death, cardiac surgery or recurrent embolism was 98 ± 1% at 5 years. CONCLUSION Percutaneous transcatheter interatrial septal defect closure is a safe and effective treatment in adults patients, even in case of thrombophilia or pulmonary hypertension, during a long-term follow-up, up to 11 years.

Abstract
Infantile myofibromatosis is a rare disorder characterized by the formation of tumors in the skin, soft tissues, bone, and viscera. We report the case of a 3-week-old girl who presented with severe hypertension due to generalized infantile myofibromatosis including renal involvement. The infant was treated by chemotherapy and showed progressive regression of the tumors. However, her evolution was marked by the development of aneurismal dilations of the renal and iliac arteries as observed in fibromuscular dysplasia. We discuss the possibility of a link between these two mesenchymal disorders.

Abstract
AIM To investigate the birth prevalence, treatment modalities and short-term survival of children with congenital heart disease who were born in 2002. METHODS We undertook a retrospective review of medical records of all patients who were born in 2002, and were diagnosed, treated and/or followed-up in one of the seven-paediatric cardiology programmes in Belgium. RESULTS In 111 225 births, 921 children with congenital heart disease were detected, yielding a birth prevalence of 8.3 per 1000. The most frequently occurring conditions were ventricular septal defects (VSDs) (33%), ostium secundum atrial septal defects (18%) and pulmonary valve abnormalities (10%). Thirty-nine percent of the children either had a cardiosurgical operation or catheter intervention. In this study, 4% of the children died. The actuarial survival at 6 months and 1 year of age was 97% and 96%, respectively and remained stable after then. Compared to other heart defects, mortality was higher in univentricular physiology, pulmonary atresia with VSD, left ventricle outflow obstruction and tetralogy of Fallot. CONCLUSION Survival of congenital heart disease is excellent and continued to improve in the early 21st century. New therapeutic options are increasingly used. This study provides baseline data for the longitudinal follow-up of this cohort.

Abstract
INTRODUCTION Although summer and sports camps for children with congenital heart disease are organized in many countries and regions, empirical data on the effects of such camps is limited. OBJECTIVES The aim of the present study was to investigate changes in the perceived health status and habitual physical activities in children attending a special sports camp. MATERIALS AND METHODS In this longitudinal study, 25 children with congenital heart disease who participated in a three-day multi-sports camp were included. The perceived health status was measured using the Child Health Questionnaire-Child Form, CHQ-CF87, completed by the child at the start of the camp (T1), at the end of the camp (T2), and 3 months after the camp concluded (T3). Habitual physical activities were assessed by means of a modified version of the Baecke questionnaire, which was completed by one of the parents at T1 and T3. RESULTS During the sports camp, we observed significant improvements in the children's perception of their physical functioning, role-physical functioning, general health, role-emotional functioning, self-esteem, mental health, and general behavior. For physical functioning, role-emotional functioning, and family activities, high scores persisted three months after the sports camp concluded. The habitual physical activities (sport and leisure time) of the children remained unchanged. DISCUSSION AND CONCLUSION In conclusion, we propose that a special sports camp for children with congenital heart disease may improve specific dimensions of subjective health status. Our study confirms a previous report on the benefits of such camps for afflicted children. If these findings can be further corroborated in other settings, participation in sport camps should be advocated as a simple, noninvasive means to promote healthier children.

Abstract
The prevalence of congenital heart defects is approximately 1% of all live births. Identifying the genes responsible for cardiac malformation is the first step to understand pathogenesis. Heterozygous mutations in the CSX/NKX2-5 (NKX2E) gene have been identified to cause atrial septal defect (ASD) and/or atrioventricular (AV) conduction disturbance in some families. However, there is great variability in expressivity of the phenotype between the patients with a CSX/NKX2-5 mutation. We screened four sporadic patients and three index cases of families with ASD and/or conduction defects. In one of them, a CSX/NKX2-5 mutation was identified. This novel mutation (p.Tyr256X) was inherited in a three-generation family causing five individuals to have cardiac anomalies ranging from ASD to arrhythmias. Interestingly, all the observed AV conduction disturbances were at the nodal level, manifesting first as an AV block of the first degree and evolving toward a second-degree block. Atrial fibrillation, previously reported in three individuals with CSX/NKX2-5 mutations, was observed in three patients.

Abstract
A healthy 18 months old boy, is referred to our hospital for a thrilling pulsatile mass behind the left ear. Aortography in the ascending aorta shows a severe coarctation with almost interruption of the aorta between the left carotid and left subclavian artery. Both external carotid arteries provide an important collateral pathway through occipital arteries to two dilated vertebral arteries. Descending aorta is feeding by a reverse blood flow into vertebral and subclavian arteries. The child has been operated. This is an original presentation of severe coarctation of the aorta with development of an important and vital collateral pathway.

Abstract
Asymmetric positioning of internal organs is a characteristics of vertebrates. The normal left-right anatomic positioning, situs solitus, sometimes does not occur normaly, leading to laterality defects. Studies in animal models have shown that laterality decisions are mediated by a cascade of genes that lead to the asymmetric expression of Nodal, LEFTA, LEFTB and PITX2 in the lateral plate mesoderm. A search for mutations in genes implicated in left-right patterning in animal models allowed genes associated with heterotaxia defects in humans to be identified. However, these genes explain only a small percentage of human situs defects, suggesting that other genes must play a role. In this study, we report a consanguineous family of Turkish origin, composed of two unaffected parents and three children, two of whom presented Kartagener syndrome. On the basis of their family history, we hypothesize autosomal recessive mode of inheritance. A genotype analysis with polymorphic markers did not show linkage with any known genes or loci causing laterality disorders. Array CGH did not detect a duplication or microdeletion greater than 1 Mb as a possible cause. Genome wide screening using 10 K Affymetrix SNP chips was performed, allowing the identification of two regions of autozygosity, one in chromosome 1 and the other on chromosome 7. In the chromosome 1 locus, a strong candidate gene, encoding the kinesin-associated protein 3 (KIF3AP) was not mutated, based on SSCP/heteroduplex analysis and direct sequencing. These data provide a basis for the identification of a novel gene implicated in Kartagener syndrome.

Abstract
Sports camps for children with cardiac anomalies have existed for many years. However, no formal evaluation of the benefits of attending such camps has been undertaken heretofore. We assessed potential changes in the self-perceived health of children with congenital heart disease who attended a special sports camp. Thirty-one children with cardiac anomalies attended a 3-day multisports camp. Sixteen children, all of whom were 10 years or older, literate, and Dutch- or French-speaking, completed the Child Health Questionnaire (CHQ-CF87) before and after attending the camp. The scores of the children were compared with those of healthy peers by calculating mean standardized differences. After attendance at the sports camp, the children achieved significant improvements in the self-perception of their physical functioning, role functioning due to emotional problems, role functioning due to behavioral problems, mental health, and general behavior. The children's self-esteem and general behavior after the camp were significantly better than that of their healthy counterparts. We conclude that children with congenital heart disease who participate in activities at special sports camps may reap benefits in terms of their subjective health status. Although further research is needed, we recommend the participation in sport activities by children with heart defects, and more specifically their participation in sports camps.

Abstract
The authors report the cases of two neonates with retro-tracheal left pulmonary arteries (pulmonary artery sling). In the first case, there was rapid onset of cardiac failure with signs of airway compression. Echocardiography showed the vascular anomaly associated with a large ventricular septal defect (VSD). After standard radiological investigation and bronchoscopy to exclude an associated tracheo-bronchial malformation, the VSD was repaired surgically with reimplantation of the left pulmonary artery. Unfortunately, the patient died of major airways obstruction in the postoperative period. Autopsy showed tracheo-bronchial anomalies which had not been diagnosed preoperatively. The second patient presented with hypoventilation of the right lung. After echocardiographic diagnosis of the anomaly, a thorough investigation (thoracic CT, helicoidal scan, bronchoscopy) was carried out and no associated bronchial malformations were observed. Reimplantation of the left pulmonary artery was successful and the postoperative course was uneventful. Retro-tracheal left pulmonary artery is a rare malformation Which is difficult to diagnose. It requires extensive pulmonary investigations and a multi-disciplinary approach. The prognosis is poor when there are associated tracheo-bronchial malformations.

Abstract
Basic fluid dynamic principles were used to derive a theoretical model of optimum cardiovascular allometry, the relationship between somatic and cardiovascular growth. The validity of the predicted models was then tested against the size of 22 cardiovascular structures measured echocardiographically in 496 normal children aged 1 day to 20 yr, including valves, pulmonary arteries, aorta and aortic branches, pulmonary veins, and left ventricular volume. Body surface area (BSA) was found to be a more important determinant of the size of each of the cardiovascular structures than age, height, or weight alone. The observed vascular and valvar dimensions were in agreement with values predicted from the theoretical models. Vascular and valve diameters related linearly to the square root of BSA, whereas valve and vascular areas related to BSA. The relationship between left ventricular volume and body size fit a complex model predicted by the nonlinear decrease of heart rate with growth. Overall, the relationship between cardiac output and body size is the fundamental driving factor in cardiovascular allometry.

Abstract
UNLABELLED Down's syndrome is the most frequent chromosomic anomaly. Fifty percent are associated with a congenital heart disease. Life expectancy and quality of life are increasing since 15 years with improving surgical techniques. PATIENTS AND METHODS This study presents 73 patients with Down's syndrome who underwent a surgical repair of congenital heart disease between 1992 and 2002. Among them, 37 (50.6%) had a complete atrio-ventricular septal defect (AVSD) and 36 an other anomaly. RESULTS Five children died in the post operative period: all had an AVSD. Two late deaths occurred due to extra cardiac causes during the follow up. Two children who underwent a repair of AVSD had to be reoperated. The majority of the children are doing well, without any cardiac symptom. Thirty-eight percent of patients with AVSD repair have a middle mitral or tricuspid regurgitation and three had a massive mitral or tricuspid regurgitation. One child presents neurological sequelae related to surgery. CONCLUSION Congenital heart diseases in Down's syndrome can be repaired with a limited risk of death. Final results are good for many children with significant improvement of the quality of life and life expectancy.

Abstract
BACKGROUND Life expectancy of patients who underwent atrial switch operation for the transposition of the great arteries is relatively good. However, many patients are faced with residua and sequelae, which may hamper their functioning and quality of life. This multicenter study assessed the perceived health status, functional abilities, and quality of life in long-term survivors of the Mustard or Senning operation. METHODS A group of 89 patients (58% male) were selected from four tertiary care centers, consisting of 37 Mustard and 52 Senning operation patients. Perceived health status was measured using a linear analog scale. The educational level, employment status, New York Health Association classification, ability index, and Baecke questionnaire were used to evaluate functional abilities. Quality of life was assessed with a linear analog scale, the Satisfaction with Life Scale, and the Congenital Heart Disease-TNO/AZL Adult Quality of Life. RESULTS Patients reported good to very good perceived health, functional capacities, and quality of life. The responses of patients with complex transposition were equivalent to those of patients with simple transposition. The most dominant concerns reported by survivors of the Mustard and Senning operations were experiences about physical limitations and worries about a current or future job or income. CONCLUSIONS Long-term survivors after atrial inflow correction demonstrated favorable perceived health, functional status, and quality of life; these conditions were, to a large extent, comparable with the status of the general population. These outcome variables were not negatively affected by the complexity of the transposition.

Abstract
BACKGROUND AND AIM OF THE STUDY Right ventricular dilatation observed after tetralogy of Fallot repair regresses after pulmonary valve implantation, unless the dilation is too severe. The presence of an akinetic patch in the right ventricular outflow tract (RVOT), a known factor promoting right ventricular dilatation, may prevent right ventricular recovery after valve implantation. The exclusion of a large akinetic RVOT area during reoperation of patients presenting with severe post-repair right ventricular dilatation was investigated. METHODS Eight patients underwent a pulmonary infundibuloplasty between May 2000 and October 2002. Their mean preoperative cardothoracic index was 0.66 +/- 0.08, and preoperative NYHA class II (n = 4), III (n = 3) or IV (n = 1). Three patients were offered heart transplantation but refused. All had severe pulmonary regurgitation and underwent a RVOT valve implantation except one patient who had a previous homograft pulmonary valve insertion. Concomitant procedures were tricuspid ring implantation (n = 3), atrial septal defect closure (n = 2), mitral valve repair (n = 1) and modified right atrial Maze (n = 1). RESULTS Median follow up time was 13 months (range: 6 -29 months). One patient suffered a fatal ventricular fibrillation at home. All patients but one were in NYHA class I. After a mean of 5 +/- 3 months, their mean workload capacity rose from 115 +/- 19 W to 155 +/- 62 W, and mean VO2max rose from 16.5 +/- 2 to 18.3 +/- 2 ml/min/kg. CONCLUSION Pulmonary infundibuloplasty may be a useful adjunct in reoperation of tetralogy of Fallot patients presenting with severe right ventricular dilatation and large akinetic area of the RVOT.

Abstract
OBJECTIVE To assess long term outcome of patients who underwent Mustard or Senning repair for transposition of the great arteries up to 30 years earlier. DESIGN Retrospective review of medical records. SETTING The six university hospitals in Belgium with paediatric cardiology departments. PATIENTS 339 patients were reviewed, of whom 124 underwent the Mustard procedure and 215 the Senning procedure. This represents almost the entire population of patients in Belgium with either simple or complex transposition. MAIN OUTCOME MEASURES Mortality, morbidity, functional abilities, social integration. RESULTS Overall mortality was 24.2%. Early mortality (< or = 30 days after surgery) accounted for 16.5%, late mortality for 7.7%. Actuarial survival of early survivors at 10, 20, and 30 years after surgery was 91.7%, 88.6%, and 79.3%, respectively. Patients in the Senning cohort had a slightly better survival rate than those in the Mustard cohort (NS). Baffle obstruction occurred more often after Mustard repair (15.3%) than after the Senning procedure (1.4%). Arrhythmia-free survival did not differ between the two cohorts, but was determined by the complexity of the transposition. Survivors of the Senning cohort had better functional status, and tended to engage in more sports activities. CONCLUSIONS The long term outcome for patients surviving the Mustard or Senning operation was favourable in terms of late mortality, morbidity, functional, and social status. Overall mortality in the Senning cohort did not differ from the Mustard group, but Senning patients had better functional status, greater participation in sports activities, and fewer baffle related problems.

Abstract
Despite providing a physiological correction, measurements of contractility using the midwall stress-velocity relationship still show evidence of an unexplained hypercontractile state in some children. We investigated if by using midwall shortening indexes, the known overestimation of contractility at low afterload could be prevented. In 12 piglets (5 or 6 weeks old), afterload was manipulated by balloon occlusion of the descending aorta and infusion of sodium nitroprusside up to 5 mg/kg/min, and left ventricular function was measured using multiple variables. The regression line between the echocardiographically derived midwall velocity of circumferential fiber shortening and end systolic wall stress differed from the regression line of the endocardial stress-velocity relationship. Although the midwall regression line was almost horizontal (or afterload independent) for end systolic wall stress values of more than 30 g/cm2, the slope was still steeper below a certain point of afterload. The increased midwall velocity of fiber shortening at low afterload is comparable to the endocardial stress-velocity relationship and could account for the pseudo-hypercontractile state found in some children.

Abstract
Non-syndromic cardiac septation defects are common, yet the causative factors remain largely uncharacterised. Septation defects are an integral part of many syndromes, some of which are associated with chromosomal alterations. For the majority, the physiopathogenesis is believed to be multi-factorial, hindering the identification of causative factors. Ten mutations in the gene encoding the transcription factor CSX/NKX2-5 have been described in individuals with ASD and/or atrioventricular conduction defects. In addition, several other cardiac abnormalities were observed, yet the mildest forms are reminiscent of non-syndromic septation defects. The CSX/NKX2-5 gene is thus a good candidate for various cardiopathies. We have collected two families with inherited predisposition to cardiac abnormalities. Some members of the families presented ASD and AV block. In both families a novel CSX/NKX2-5 mutation was identified in the homeodomain. Variable expressivity in the phenotype was observed in both families. Importantly, mutation carriers did not present any symptoms at young age. In addition, anomalous venous return, a phenotype not previously associated to CSX/NKX2-5 mutations, was observed in one of the families. We also screened the CSX/NKX2-5 gene in sporadic and familial cases of other cardiopathies. As additional mutations were not found, substitutions in CSX/NKX2-5 gene seem to be a rare cause of cardiopathies without conduction defect.

Abstract
BACKGROUND Elevated right ventricle pressure resulting from pulmonary artery stenoses may affect outcome and survival after liver transplantation in patients with Alagille syndrome. METHODS AND RESULTS Between 1984 and 1997, among 444 pediatric liver transplant recipients, 17 had liver transplantation for Alagille syndrome (mean age 3.5 years, range 1.2-13 years), mainly because of poor quality of life with intractable pruritus, and failure to thrive. All patients had pulmonary artery stenosis. In 10 patients considered to have elevated RV pressure on ECG and/or Doppler-echocardiography, a cardiac catheterization was performed before liver transplantation. Mean RV systolic pressure was 55 mmHg (median 49.5 mmHg, range 35-98 mm Hg), mean RV to left ventricular systolic pressure ratio 0.53 (median 0.53, range 0.29-0.78) with a ratio above 0.5 in 6 patients (median 0.66, range 0.5-0.8). All patients underwent successful liver transplantation. Five patients died 1 to 9 months after transplantation from noncardiac causes. In two of them, cardiac catheterization before transplantation showed a RV to left ventricular pressure ratio of 0.51 in one and 0.37 in the second. In the three others, echocardiography before transplantation estimated RV pressures below 0.5 systemic pressures. At follow-up (median 6 years, range 1.5-15 years), liver tests were normal in all, none complained of pruritus and body weight was normalized in 70%. None of the patients presented cardiac symptoms, arrhythmias, or worsening of their cardiac status. CONCLUSIONS Liver transplantation can be performed safely in children with Alagille syndrome, even in the presence of elevated right ventricular pressure.

Abstract
BACKGROUND In tetralogy of Fallot, transannular patching is suspected to be responsible for late right ventricular dilatation. METHODS AND RESULTS In our institution, 191 patients survived a tetralogy of Fallot repair between 1964 and 1984. Transannular patching was used in 99 patients (52%), patch closure of a right ventriculotomy in 35, and direct closure of a right ventriculotomy in 55. Two had a transatrial-transpulmonary approach. To identify predictive factors of adverse long-term outcome related to right ventricular dilatation, the following events were investigated: cardiac death, reoperation for symptomatic right ventricular dilatation, and NYHA class II or III by Cox regression analysis. Mean follow-up reached 22+/-5 years. The 30-year survival was 86+/-5%. Right ventricular patching, whether transannular or not, was the most significant independent predictor of late adverse event (improvement chi(2)=16.6, P:<0.001). In patients who had direct closure, the ratio between end-diastolic right and left ventricular dimensions on echocardiography was smaller (0.61+/-0.017 versus 0. 75+/-0.23, P:=0.007), with a smaller proportion presenting severe pulmonary insufficiency (9% versus 40%, P:=0.005). There was no difference between right ventricular and transannular patching concerning late outcome (log rank P: value=0.6), right ventricular size (0.70+/-0.28 versus 0.76+/-0.26, P:=0.4), or incidence of severe pulmonary insufficiency (30% versus 43%, P:=0.3). CONCLUSIONS In tetralogy of Fallot, transannular patching does not result in a worse late functional outcome than patching of an incision limited to the right ventricle. Both are responsible for a similar degree of long-term pulmonary insufficiency and right ventricular dilatation.

Abstract
UNLABELLED Children with Alagille's syndrome are at increased perioperative risk during orthotopic liver transplantation due to the cardiopulmonary abnormalities and the hemodynamic changes associated with this procedure. We studied 16 children with Alagille's syndrome who underwent 21 orthotopic liver transplantations. Peripheral pulmonary stenosis was present in all subjects. Right ventricular pressures were increased in 15 cases. Caval clamping resulted in a mean decrease of 15 +/-9 mm Hg in systolic blood pressure, 5 +/- 3 mm Hg in mean pulmonary artery pressure, and 4 +/- 3 mm Hg in central venous pressure. Systolic blood pressure decreased by 16 +/- 13 mm Hg, whereas mean pulmonary artery pressure and central venous pressure increased by 3 +/- 4 mm Hg and 1 +/- 4 mm Hg, respectively, at portal vein unclamping. There was no correlation between severity of pulmonary artery stenosis and hemodynamic changes. Veno-venous bypass used in four cases resulted in smaller hemodynamic changes. Time to extubation and duration of intensive care unit stay were unrelated to severity of pulmonary artery stenosis. IMPLICATIONS Some children with Alagille's syndrome require liver transplantation. In our study, associated pulmonary artery stenosis did not dramatically increase perioperative risk. Veno-venous bypass decreased intraoperative hemodynamic changes in these patients.

Abstract
BACKGROUND The Ross operation, although more demanding, is now widely accepted as an alternative solution for aortic valve replacement in young adults and children. A review of our experience to assess the mid-term results with the Ross operation is presented. METHODS From June 1991 through October 1997, 80 patients (mean age, 31 years) underwent aortic valve or root replacement with pulmonary autografts. Indications for operation were predominant aortic stenosis in 38 patients, aortic incompetence in 42 patients including endocarditis in 3 patients. Congenital lesions were present in 57 patients, either at pediatric (27 patients) or adult age (30 patients). Transthoracic echocardiography was performed preoperatively in all patients and serially after operation with the aims of measuring aortic and pulmonary annuli, evaluating transvalvular gradients and incompetence, and studying the left ventricular function. Intraoperative transesophageal echocardiography was used routinely. Complete root replacement was performed in 52 patients, intraluminal cylinder in 25 patients, and subcoronary implantation in 3 patients. RESULTS One patient died in the early postoperative period (1.2%). There was no late death. The actuarial survival at 5 years was 98%+/-1%. All survivors remained in New York Heart Association functional class I and were free of complications and medications. No gradient or significant aortic incompetence could be demonstrated in 73 patients. One patient developed late aortic incompetence grade 3 and reoperation is considered. On the pulmonary outflow tract, 6 patients had gradients between 20 and 40 mm Hg as calculated on echocardiography. CONCLUSIONS The pulmonary autograft gives excellent mid-term results with low mortality and no morbidity. It completely relieves the abnormal loading conditions of the left ventricle, resulting in a complete recovery of left ventricular function in most patients.

Abstract
The relation between systolic meridional wall stress (WS) and velocity of circumferential fiber shortening (VcFc) is widely accepted as a preload-independent index of contractility, with a linear relation in most subjects older than 2 y. However, this relation seems to become different in infants and after administration of inotropic agents. We decided to study the nature of the stress-velocity relation by a cross-sectional assessment of the influence of age, low afterload, and increased contractility. Study subjects were 30 healthy infants, 32 healthy older children, and 35 asymptomatic older children after completion of anthracycline chemotherapy. WS and VcFc at rest were studied in these infants and children. WS and VcFc were also studied after dobutamine infusion in both groups of older children. Linear regression analysis of the stress-velocity relation showed parallel slopes between the older children at rest and the post anthracycline children after dobutamine. The regression lines between the infants at rest and the healthy older children after dobutamine were also parallel, but with a different and steeper slope compared with the former groups. When comparing the stress-velocity relation of the overall population at rest with the overall population after dobutamine, the resulting regression lines are curvilinear and parallel, with a steeper slope at low afterload. The stress-velocity relation in infants and after dobutamine, resulting in low afterload is different compared with the stress- velocity relation in older children at rest and at higher afterload. Data of the overall population at rest and after dobutamine suggest a curvilinear relation.

Abstract
BACKGROUND AND AIMS OF THE STUDY Transannular patch repair of tetralogy of Fallot leads to pulmonary insufficiency and progressive right ventricular dilatation responsible for a decreased exercise capacity. We studied the impact of late homograft insertion on the regression of the right ventricular volumes in symptomatic patients. METHODS Between July 1992 and August 1996, 15 consecutive patients (age range: 4 to 24 years) were operated on at a median of 13 years (range: 3 to 20 years) after transannular patch repair of tetralogy of Fallot. All patients complained of exertional dyspnea and fatigue. Syncopes were reported in six patients and four patients had sustained episodes of ventricular tachycardia. Fourteen had pulmonary regurgitation grade 3 or 4 and one had an associated stenosis and insufficiency. All patients had a dilated right ventricle. At reoperation, no patients presented with major aneurysm. The patch was resected and the right ventricular outflow tract reconstructed with a cryopreserved pulmonary homograft. Right ventricular volumes were studied before the procedures and at the last follow up consultation. RESULTS There was no operative death. One patient who had a concomitant patch repair of a hypoplastic left pulmonary artery needed extracorporeal circulatory support for eight days. After a median follow up of 25 months (range: 3 to 54 months) all patients but one are in NYHA class I. There were no late deaths. The mean end-diastolic diameter of the right ventricle decreased from 36 +/- 9 mm before surgery to 31 +/- 6 mm (not significant). The mean ratio between the end-diastolic diameter of the right and left ventricles decreased from 0.94 +/- 0.3 to 0.74 +/- 0.2 (p < 0.01). CONCLUSION An increasing number of patients who had transannular patch repair for tetralogy of Fallot will require reoperation for symptomatic long-term pulmonary regurgitation. Homograft reconstruction of the right ventricular outflow tract of these patients induces regression of their right ventricular dilatation and leads to their functional recovery.

Abstract
Between April 1990 and August 1996, 138 patients (median age 42 years, range 10 days to 66 years) underwent aortic valve or root replacement with allografts (n = 70) or autografts (n = 68). Aortic stenosis was the main indication (80 patients, 58%) followed by aortic incompetence (31 patients, 22%). Twenty-five patients had endocarditis (18%) and two patients had truncus repair (2%). Some 140 allograft valves were inserted (70 pulmonary, 70 aortic). Most of the valves were conditioned and cryopreserved by the European Homograft Bank, Brussels, Belgium. Subcoronary implantation was performed in 46 patients, intraluminal cylinder in 29 and root replacement in 63. Peroperative transoesophageal echocardiography was routinely used. Three patients required valves replacement by mechanical valves at the time of surgery due to technical failure. Seven patients (5%) died early, while 131 were followed up from 1 to 76 months (mean 32 months). There were two late deaths. All survivors are in NYHA class I and currently free of any medication. There have been no thromboembolic events. Three patients developed endocarditis (2%). Transthoracic echocardiography was performed routinely in all patients; an initial study showed grade 1 aortic incompetence in nine patients and grade 2 in two. Late studies up to 6 years after surgery showed progression of aortic incompetence in 18 of 43 survivors with subcoronary implantation and in four of 75 survivors who underwent other techniques (P < 0.002). In congenital patients with preoperative aortic incompetence, the left ventricular function has been prospectively analysed by echocardiography. Risk factors have been identified as dilated ventricles with spherical shapes, thin wall and reduced velocities by measuring ejection fraction and velocity of shortening of myocardial fibres. Allograft and autograft replacement of the aortic valve can be performed with excellent results. Considering the risk of degeneration of allografts, and the growth potential of the pulmonary autograft, this should be regarded as the optimal method of treatment for diseased aortic valves in neonates, children and young adults.

Abstract
A boy had neonatal seizure, lethargy, and metabolic acidosis at presentation. He recovered completely, but the recurrence of a similar episode with associated cardiomyopathy and dicarboxylic aciduria at 10 months of age led to the recognition of a fatty acid oxidation defect. A diagnosis of very long chain acyl-coenzyme A dehydrogenase deficiency was later made by enzyme assay in culture fibroblasts from this child, as well as in cultured amniotic cells from a sibling fetus. This prenatal diagnosis forestalled neonatal injury by close clinical and metabolic monitoring of the second infant. Early diagnosis and management should potentially improve the generally poor prognosis for patients with very long chain acyl-coenzyme A dehydrogenase deficiency.

Abstract
A case of successfully operated neonatal ductus arteriosus aneurysm is described. Cardiac catheterization was performed to confirm the diagnosis because of a misinterpretation of the anatomy on transthoracic echocardiography. Rupture, embolism and infection are described complications of such aneurysms. Surgery should therefore be recommended without delay.

Abstract
Occurrence of endocarditis after surgical repair of tetralogy of Fallot is rare. A case of early postoperative endocarditis in a 1-year-old infant is described. At reoperation an abscess of the the tricuspid valve annulus was discovered at the site of implantation of the ventricular septal defect patch. After debridement of the annulus, the septal and the anterior leaflet of the tricuspid valve were found dehiscent from their annular insertion. The tricuspid annulus was reconstructed with a patch of autologous pericardium, and the preserved leaflets were reimplanted.
